rhynchosia rufescens/protease

Crude proteinase inhibitors (CPIs) extracted from the seeds of Rhynchosia sublobata, a wild relative of pigeon pea showed pronounced inhibitory activity on the larval gut trypsin-like proteases of lepidopteran insect pest - Achaea janata. Consequently, a full-length cDNA of Bowman-Birk inhibitor

Rhynchosia sublobata, a wild relative of pigeonpea, possesses defensive proteinase/protease inhibitors (PIs). Characterization of trypsin specific PIs (RsPI) separated from seeds by column chromatography using 2-D gel electrophoresis and Edman degradation method identified R. sublobata possessed

Four new prenylated isoflavones, rhynedulins A-C (1-3) and rhynedulinal (4), were isolated by bioassay-guided fractionation of the dichloromethane bark extract of Rhynchosia edulis. Five previously described compounds, scandenal, ulexin B, cajanone, cajanin, and cyclochandalone, were also isolated.
